Heirloom tomatoes are those tomatoes that are open-pollinated rather than hybrid or genetically modified varieties of tomatoes.
Some of these varieties were grown regionally by gardeners who saved the seeds each year and passed them on to family or friends in the area. Now, as these unique heirlooms are being “rediscovered” more and more heirloom varieties are being offered for sale nationally.
Here is a list of some popular, or unique, red heirloom tomatoes as well as the amount of days from transplanting to maturity, and a description of the fruit size. All these heirloom tomatoes are indeterminate unless otherwise stated.
